Judging Facebook’s Privacy Shift

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2019/03/judging_faceboo.html

Facebook is making a new and stronger commitment to privacy. Last month, the company hired three of its most vociferous critics and installed them in senior technical positions. And on Wednesday, Mark Zuckerberg wrote that the company will pivot to focus on private conversations over the public sharing that has long defined the platform, even while conceding that “frankly we don’t currently have a strong reputation for building privacy protective services.”

There is ample reason to question Zuckerberg’s pronouncement: The company has made — and broken — many privacy promises over the years. And if you read his 3,000-word post carefully, Zuckerberg says nothing about changing Facebook’s surveillance capitalism business model. All the post discusses is making private chats more central to the company, which seems to be a play for increased market dominance and to counter the Chinese company WeChat.

In security and privacy, the devil is always in the details — and Zuckerberg’s post provides none. But we’ll take him at his word and try to fill in some of the details here. What follows is a list of changes we should expect if Facebook is serious about changing its business model and improving user privacy.

How Facebook treats people on its platform

Increased transparency over advertiser and app accesses to user data. Today, Facebook users can download and view much of the data the company has about them. This is important, but it doesn’t go far enough. The company could be more transparent about what data it shares with advertisers and others and how it allows advertisers to select users they show ads to. Facebook could use its substantial skills in usability testing to help people understand the mechanisms advertisers use to show them ads or the reasoning behind what it chooses to show in user timelines. It could deliver on promises in this area.

Better — and more usable — privacy options. Facebook users have limited control over how their data is shared with other Facebook users and almost no control over how it is shared with Facebook’s advertisers, which are the company’s real customers. Moreover, the controls are buried deep behind complex and confusing menu options. To be fair, some of this is because privacy is complex, and it’s hard to understand the results of different options. But much of this is deliberate; Facebook doesn’t want its users to make their data private from other users.

The company could give people better control over how — and whether — their data is used, shared, and sold. For example, it could allow users to turn off individually targeted news and advertising. By this, we don’t mean simply making those advertisements invisible; we mean turning off the data flows into those tailoring systems. Finally, since most users stick to the default options when it comes to configuring their apps, a changing Facebook could tilt those defaults toward more privacy, requiring less tailoring most of the time.

More user protection from stalking. “Facebook stalking” is often thought of as “stalking light,” or “harmless.” But stalkers are rarely harmless. Facebook should acknowledge this class of misuse and work with experts to build tools that protect all of its users, especially its most vulnerable ones. Such tools should guide normal people away from creepiness and give victims power and flexibility to enlist aid from sources ranging from advocates to police.

Fully ending real-name enforcement. Facebook’s real-names policy, requiring people to use their actual legal names on the platform, hurts people such as activists, victims of intimate partner violence, police officers whose work makes them targets, and anyone with a public persona who wishes to have control over how they identify to the public. There are many ways Facebook can improve on this, from ending enforcement to allowing verifying pseudonyms for everyone­ — not just celebrities like Lady Gaga. Doing so would mark a clear shift.

How Facebook runs its platform

Increased transparency of Facebook’s business practices. One of the hard things about evaluating Facebook is the effort needed to get good information about its business practices. When violations are exposed by the media, as they regularly are, we are all surprised at the different ways Facebook violates user privacy. Most recently, the company used phone numbers provided for two-factor authentication for advertising and networking purposes. Facebook needs to be both explicit and detailed about how and when it shares user data. In fact, a move from discussing “sharing” to discussing “transfers,” “access to raw information,” and “access to derived information” would be a visible improvement.

Increased transparency regarding censorship rules. Facebook makes choices about what content is acceptable on its site. Those choices are controversial, implemented by thousands of low-paid workers quickly implementing unclear rules. These are tremendously hard problems without clear solutions. Even obvious rules like banning hateful words run into challenges when people try to legitimately discuss certain important topics. Whatever Facebook does in this regard, the company needs be more transparent about its processes. It should allow regulators and the public to audit the company’s practices. Moreover, Facebook should share any innovative engineering solutions with the world, much as it currently shares its data center engineering.

Better security for collected user data. There have been numerous examples of attackers targeting cloud service platforms to gain access to user data. Facebook has a large and skilled product security team that says some of the right things. That team needs to be involved in the design trade-offs for features and not just review the near-final designs for flaws. Shutting down a feature based on internal security analysis would be a clear message.

Better data security so Facebook sees less. Facebook eavesdrops on almost every aspect of its users’ lives. On the other hand, WhatsApp — purchased by Facebook in 2014 — provides users with end-to-end encrypted messaging. While Facebook knows who is messaging whom and how often, Facebook has no way of learning the contents of those messages. Recently, Facebook announced plans to combine WhatsApp, Facebook Messenger, and Instagram, extending WhatsApp’s security to the consolidated system. Changing course here would be a dramatic and negative signal.

Collecting less data from outside of Facebook. Facebook doesn’t just collect data about you when you’re on the platform. Because its “like” button is on so many other pages, the company can collect data about you when you’re not on Facebook. It even collects what it calls “shadow profiles” — data about you even if you’re not a Facebook user. This data is combined with other surveillance data the company buys, including health and financial data. Collecting and saving less of this data would be a strong indicator of a new direction for the company.

Better use of Facebook data to prevent violence. There is a trade-off between Facebook seeing less and Facebook doing more to prevent hateful and inflammatory speech. Dozens of people have been killed by mob violence because of fake news spread on WhatsApp. If Facebook were doing a convincing job of controlling fake news without end-to-end encryption, then we would expect to hear how it could use patterns in metadata to handle encrypted fake news.

How Facebook manages for privacy

Create a team measured on privacy and trust. Where companies spend their money tells you what matters to them. Facebook has a large and important growth team, but what team, if any, is responsible for privacy, not as a matter of compliance or pushing the rules, but for engineering? Transparency in how it is staffed relative to other teams would be telling.

Hire a senior executive responsible for trust. Facebook’s current team has been focused on growth and revenue. Its one chief security officer, Alex Stamos, was not replaced when he left in 2018, which may indicate that having an advocate for security on the leadership team led to debate and disagreement. Retaining a voice for security and privacy issues at the executive level, before those issues affected users, was a good thing. Now that responsibility is diffuse. It’s unclear how Facebook measures and assesses its own progress and who might be held accountable for failings. Facebook can begin the process of fixing this by designating a senior executive who is responsible for trust.

Engage with regulators. Much of Facebook’s posturing seems to be an attempt to forestall regulation. Facebook sends lobbyists to Washington and other capitals, and until recently the company sent support staff to politician’s offices. It has secret lobbying campaigns against privacy laws. And Facebook has repeatedly violated a 2011 Federal Trade Commission consent order regarding user privacy. Regulating big technical projects is not easy. Most of the people who understand how these systems work understand them because they build them. Societies will regulate Facebook, and the quality of that regulation requires real education of legislators and their staffs. While businesses often want to avoid regulation, any focus on privacy will require strong government oversight. If Facebook is serious about privacy being a real interest, it will accept both government regulation and community input.

User privacy is traditionally against Facebook’s core business interests. Advertising is its business model, and targeted ads sell better and more profitably — and that requires users to engage with the platform as much as possible. Increased pressure on Facebook to manage propaganda and hate speech could easily lead to more surveillance. But there is pressure in the other direction as well, as users equate privacy with increased control over how they present themselves on the platform.

We don’t expect Facebook to abandon its advertising business model, relent in its push for monopolistic dominance, or fundamentally alter its social networking platforms. But the company can give users important privacy protections and controls without abandoning surveillance capitalism. While some of these changes will reduce profits in the short term, we hope Facebook’s leadership realizes that they are in the best long-term interest of the company.

Facebook talks about community and bringing people together. These are admirable goals, and there’s plenty of value (and profit) in having a sustainable platform for connecting people. But as long as the most important measure of success is short-term profit, doing things that help strengthen communities will fall by the wayside. Surveillance, which allows individually targeted advertising, will be prioritized over user privacy. Outrage, which drives engagement, will be prioritized over feelings of belonging. And corporate secrecy, which allows Facebook to evade both regulators and its users, will be prioritized over societal oversight. If Facebook now truly believes that these latter options are critical to its long-term success as a company, we welcome the changes that are forthcoming.

On Surveillance in the Workplace

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2019/03/on_surveillance.html

Data & Society just published a report entitled “Workplace Monitoring & Surveillance“:

This explainer highlights four broad trends in employee monitoring and surveillance technologies:

  • Prediction and flagging tools that aim to predict characteristics or behaviors of employees or that are designed to identify or deter perceived rule-breaking or fraud. Touted as useful management tools, they can augment biased and discriminatory practices in workplace evaluations and segment workforces into risk categories based on patterns of behavior.
  • Biometric and health data of workers collected through tools like wearables, fitness tracking apps, and biometric timekeeping systems as a part of employer- provided health care programs, workplace wellness, and digital tracking work shifts tools. Tracking non-work-related activities and information, such as health data, may challenge the boundaries of worker privacy, open avenues for discrimination, and raise questions about consent and workers’ ability to opt out of tracking.

  • Remote monitoring and time-tracking used to manage workers and measure performance remotely. Companies may use these tools to decentralize and lower costs by hiring independent contractors, while still being able to exert control over them like traditional employees with the aid of remote monitoring tools. More advanced time-tracking can generate itemized records of on-the-job activities, which can be used to facilitate wage theft or allow employers to trim what counts as paid work time.

  • Gamification and algorithmic management of work activities through continuous data collection. Technology can take on management functions, such as sending workers automated “nudges” or adjusting performance benchmarks based on a worker’s real-time progress, while gamification renders work activities into competitive, game-like dynamics driven by performance metrics. However, these practices can create punitive work environments that place pressures on workers to meet demanding and shifting efficiency benchmarks.

In a blog post about this report, Cory Doctorow mentioned “the adoption curve for oppressive technology, which goes, ‘refugee, immigrant, prisoner, mental patient, children, welfare recipient, blue collar worker, white collar worker.'” I don’t agree with the ordering, but the sentiment is correct. These technologies are generally used first against people with diminished rights: prisoners, children, the mentally ill, and soldiers.

Detecting Shoplifting Behavior

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2019/03/detecting_shopl.html

This system claims to detect suspicious behavior that indicates shoplifting:

Vaak, a Japanese startup, has developed artificial intelligence software that hunts for potential shoplifters, using footage from security cameras for fidgeting, restlessness and other potentially suspicious body language.

The article has no detail or analysis, so we don’t know how well it works. But this kind of thing is surely the future of video surveillance.

The Latest in Creepy Spyware

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2019/03/the_latest_in_c.html

The Nest home alarm system shipped with a secret microphone, which — according to the company — was only an accidental secret:

On Tuesday, a Google spokesperson told Business Insider the company had made an “error.”

“The on-device microphone was never intended to be a secret and should have been listed in the tech specs,” the spokesperson said. “That was an error on our part.”

Where are the consumer protection agencies? They should be all over this.

And while they’re figuring out which laws Google broke, they should also look at American Airlines. Turns out that some of their seats have built-in cameras:

American Airlines spokesperson Ross Feinstein confirmed to BuzzFeed News that cameras are present on some of the airlines’ in-flight entertainment systems, but said “they have never been activated, and American is not considering using them.” Feinstein added, “Cameras are a standard feature on many in-flight entertainment systems used by multiple airlines. Manufacturers of those systems have included cameras for possible future uses, such as hand gestures to control in-flight entertainment.”

That makes it all okay, doesn’t it?

Actually, I kind of understand the airline seat camera thing. My guess is that whoever designed the in-flight entertainment system just specced a standard tablet computer, and they all came with unnecessary features like cameras. This is how we end up with refrigerators with Internet connectivity and Roombas with microphones. It’s cheaper to leave the functionality in than it is to remove it.

Still, we need better disclosure laws.

Reverse Location Search Warrants

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2019/02/reverse_locatio.html

The police are increasingly getting search warrants for information about all cell phones in a certain location at a certain time:

Police departments across the country have been knocking at Google’s door for at least the last two years with warrants to tap into the company’s extensive stores of cellphone location data. Known as “reverse location search warrants,” these legal mandates allow law enforcement to sweep up the coordinates and movements of every cellphone in a broad area. The police can then check to see if any of the phones came close to the crime scene. In doing so, however, the police can end up not only fishing for a suspect, but also gathering the location data of potentially hundreds (or thousands) of innocent people. There have only been anecdotal reports of reverse location searches, so it’s unclear how widespread the practice is, but privacy advocates worry that Google’s data will eventually allow more and more departments to conduct indiscriminate searches.

Of course, it’s not just Google who can provide this information.

I am also reminded of a Canadian surveillance program disclosed by Snowden.

I spend a lot of time talking about this sort of thing in Data and Goliath. Once you have everyone under surveillance all the time, many things are possible.

Facebook’s New Privacy Hires

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2019/02/facebooks_new_p.html

The Wired headline sums it up nicely — “Facebook Hires Up Three of Its Biggest Privacy Critics“:

In December, Facebook hired Nathan White away from the digital rights nonprofit Access Now, and put him in the role of privacy policy manager. On Tuesday of this week, lawyers Nate Cardozo, of the privacy watchdog Electronic Frontier Foundation, and Robyn Greene, of New America’s Open Technology Institute, announced they also are going in-house at Facebook. Cardozo will be the privacy policy manager of WhatsApp, while Greene will be Facebook’s new privacy policy manager for law enforcement and data protection.

I know these people. They’re ethical, and they’re on the right side. I hope they continue to do their good work from inside Facebook.

Human Rights by Design

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/12/human_rights_by.html

Good essay: “Advancing Human-Rights-By-Design In The Dual-Use Technology Industry,” by Jonathon Penney, Sarah McKune, Lex Gill, and Ronald J. Deibert:

But businesses can do far more than these basic measures. They could adopt a “human-rights-by-design” principle whereby they commit to designing tools, technologies, and services to respect human rights by default, rather than permit abuse or exploitation as part of their business model. The “privacy-by-design” concept has gained currency today thanks in part to the European Union General Data Protection Regulation (GDPR), which requires it. The overarching principle is that companies must design products and services with the default assumption that they protect privacy, data, and information of data subjects. A similar human-rights-by-design paradigm, for example, would prevent filtering companies from designing their technology with features that enable large-scale, indiscriminate, or inherently disproportionate censorship capabilities­ — like the Netsweeper feature that allows an ISP to block entire country top level domains (TLDs). DPI devices and systems could be configured to protect against the ability of operators to inject spyware in network traffic or redirect users to malicious code rather than facilitate it. And algorithms incorporated into the design of communications and storage platforms could account for human rights considerations in addition to business objectives. Companies could also join multi-stakeholder efforts like the Global Network Initiative (GNI), through which technology companies (including Google, Microsoft, and Yahoo) have taken the first step toward principles like transparency, privacy, and freedom of expression, as well as to self-reporting requirements and independent compliance assessments.

How Surveillance Inhibits Freedom of Expression

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/11/how_surveillanc_1.html

In my book Data and Goliath, I write about the value of privacy. I talk about how it is essential for political liberty and justice, and for commercial fairness and equality. I talk about how it increases personal freedom and individual autonomy, and how the lack of it makes us all less secure. But this is probably the most important argument as to why society as a whole must protect privacy: it allows society to progress.

We know that surveillance has a chilling effect on freedom. People change their behavior when they live their lives under surveillance. They are less likely to speak freely and act individually. They self-censor. They become conformist. This is obviously true for government surveillance, but is true for corporate surveillance as well. We simply aren’t as willing to be our individual selves when others are watching.

Let’s take an example: hearing that parents and children are being separated as they cross the US border, you want to learn more. You visit the website of an international immigrants’ rights group, a fact that is available to the government through mass Internet surveillance. You sign up for the group’s mailing list, another fact that is potentially available to the government. The group then calls or e-mails to invite you to a local meeting. Same. Your license plates can be collected as you drive to the meeting; your face can be scanned and identified as you walk into and out of the meeting. If, instead of visiting the website, you visit the group’s Facebook page, Facebook knows that you did and that feeds into its profile of you, available to advertisers and political activists alike. Ditto if you like their page, share a link with your friends, or just post about the issue.

Maybe you are an immigrant yourself, documented or not. Or maybe some of your family is. Or maybe you have friends or coworkers who are. How likely are you to get involved if you know that your interest and concern can be gathered and used by government and corporate actors? What if the issue you are interested in is pro- or anti-gun control, anti-police violence or in support of the police? Does that make a difference?

Maybe the issue doesn’t matter, and you would never be afraid to be identified and tracked based on your political or social interests. But even if you are so fearless, you probably know someone who has more to lose, and thus more to fear, from their personal, sexual, or political beliefs being exposed.

This isn’t just hypothetical. In the months and years after the 9/11 terrorist attacks, many of us censored what we spoke about on social media or what we searched on the Internet. We know from a 2013 PEN study that writers in the United States self-censored their browsing habits out of fear the government was watching. And this isn’t exclusively an American event; Internet self-censorship is prevalent across the globe, China being a prime example.

Ultimately, this fear stagnates society in two ways. The first is that the presence of surveillance means society cannot experiment with new things without fear of reprisal, and that means those experiments­ — if found to be inoffensive or even essential to society — ­cannot slowly become commonplace, moral, and then legal. If surveillance nips that process in the bud, change never happens. All social progress­ — from ending slavery to fighting for women’s rights­ — began as ideas that were, quite literally, dangerous to assert. Yet without the ability to safely develop, discuss, and eventually act on those assertions, our society would not have been able to further its democratic values in the way that it has.

Consider the decades-long fight for gay rights around the world. Within our lifetimes we have made enormous strides to combat homophobia and increase acceptance of queer folks’ right to marry. Queer relationships slowly progressed from being viewed as immoral and illegal, to being viewed as somewhat moral and tolerated, to finally being accepted as moral and legal.

In the end, it was the public nature of those activities that eventually slayed the bigoted beast, but the ability to act in private was essential in the beginning for the early experimentation, community building, and organizing.

Marijuana legalization is going through the same process: it’s currently sitting between somewhat moral, and­ — depending on the state or country in question — ­tolerated and legal. But, again, for this to have happened, someone decades ago had to try pot and realize that it wasn’t really harmful, either to themselves or to those around them. Then it had to become a counterculture, and finally a social and political movement. If pervasive surveillance meant that those early pot smokers would have been arrested for doing something illegal, the movement would have been squashed before inception. Of course the story is more complicated than that, but the ability for members of society to privately smoke weed was essential for putting it on the path to legalization.

We don’t yet know which subversive ideas and illegal acts of today will become political causes and positive social change tomorrow, but they’re around. And they require privacy to germinate. Take away that privacy, and we’ll have a much harder time breaking down our inherited moral assumptions.

The second way surveillance hurts our democratic values is that it encourages society to make more things illegal. Consider the things you do­ — the different things each of us does­ — that portions of society find immoral. Not just recreational drugs and gay sex, but gambling, dancing, public displays of affection. All of us do things that are deemed immoral by some groups, but are not illegal because they don’t harm anyone. But it’s important that these things can be done out of the disapproving gaze of those who would otherwise rally against such practices.

If there is no privacy, there will be pressure to change. Some people will recognize that their morality isn’t necessarily the morality of everyone­ — and that that’s okay. But others will start demanding legislative change, or using less legal and more violent means, to force others to match their idea of morality.

It’s easy to imagine the more conservative (in the small-c sense, not in the sense of the named political party) among us getting enough power to make illegal what they would otherwise be forced to witness. In this way, privacy helps protect the rights of the minority from the tyranny of the majority.

This is how we got Prohibition in the 1920s, and if we had had today’s surveillance capabilities in the 1920s, it would have been far more effectively enforced. Recipes for making your own spirits would have been much harder to distribute. Speakeasies would have been impossible to keep secret. The criminal trade in illegal alcohol would also have been more effectively suppressed. There would have been less discussion about the harms of Prohibition, less “what if we didn’t?” thinking. Political organizing might have been difficult. In that world, the law might have stuck to this day.

China serves as a cautionary tale. The country has long been a world leader in the ubiquitous surveillance of its citizens, with the goal not of crime prevention but of social control. They are about to further enhance their system, giving every citizen a “social credit” rating. The details are yet unclear, but the general concept is that people will be rated based on their activities, both online and off. Their political comments, their friends and associates, and everything else will be assessed and scored. Those who are conforming, obedient, and apolitical will be given high scores. People without those scores will be denied privileges like access to certain schools and foreign travel. If the program is half as far-reaching as early reports indicate, the subsequent pressure to conform will be enormous. This social surveillance system is precisely the sort of surveillance designed to maintain the status quo.

For social norms to change, people need to deviate from these inherited norms. People need the space to try alternate ways of living without risking arrest or social ostracization. People need to be able to read critiques of those norms without anyone’s knowledge, discuss them without their opinions being recorded, and write about their experiences without their names attached to their words. People need to be able to do things that others find distasteful, or even immoral. The minority needs protection from the tyranny of the majority.

Privacy makes all of this possible. Privacy encourages social progress by giving the few room to experiment free from the watchful eye of the many. Even if you are not personally chilled by ubiquitous surveillance, the society you live in is, and the personal costs are unequivocal.

The PCLOB Needs a Director

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/11/the_pclob_needs.html

The US Privacy and Civil Liberties Oversight Board is looking for a director. Among other things, this board has some oversight role over the NSA. More precisely, it can examine what any executive-branch agency is doing about counterterrorism. So it can examine the program of TSA watchlists, NSA anti-terrorism surveillance, and FBI counterterrorism activities.

The PCLOB was established in 2004 (when it didn’t do much), disappeared from 2007-2012, and reconstituted in 2012. It issued a major report on NSA surveillance in 2014. It has dwindled since then, having as few as one member. Last month, the Senate confirmed three new members, including Ed Felten.

So, potentially an important job if anyone out there is interested.

Privacy and Security of Data at Universities

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/11/privacy_and_sec.html

Interesting paper: “Open Data, Grey Data, and Stewardship: Universities at the Privacy Frontier,” by Christine Borgman:

Abstract: As universities recognize the inherent value in the data they collect and hold, they encounter unforeseen challenges in stewarding those data in ways that balance accountability, transparency, and protection of privacy, academic freedom, and intellectual property. Two parallel developments in academic data collection are converging: (1) open access requirements, whereby researchers must provide access to their data as a condition of obtaining grant funding or publishing results in journals; and (2) the vast accumulation of “grey data” about individuals in their daily activities of research, teaching, learning, services, and administration. The boundaries between research and grey data are blurring, making it more difficult to assess the risks and responsibilities associated with any data collection. Many sets of data, both research and grey, fall outside privacy regulations such as HIPAA, FERPA, and PII. Universities are exploiting these data for research, learning analytics, faculty evaluation, strategic decisions, and other sensitive matters. Commercial entities are besieging universities with requests for access to data or for partnerships to mine them. The privacy frontier facing research universities spans open access practices, uses and misuses of data, public records requests, cyber risk, and curating data for privacy protection. This Article explores the competing values inherent in data stewardship and makes recommendations for practice by drawing on the pioneering work of the University of California in privacy and information security, data governance, and cyber risk.

Privacy for Tigers

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/10/privacy_for_tig.html

Ross Anderson has some new work:

As mobile phone masts went up across the world’s jungles, savannas and mountains, so did poaching. Wildlife crime syndicates can not only coordinate better but can mine growing public data sets, often of geotagged images. Privacy matters for tigers, for snow leopards, for elephants and rhinos ­ and even for tortoises and sharks. Animal data protection laws, where they exist at all, are oblivious to these new threats, and no-one seems to have started to think seriously about information security.

How DNA Databases Violate Everyone’s Privacy

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/10/how_dna_databas.html

If you’re an American of European descent, there’s a 60% chance you can be uniquely identified by public information in DNA databases. This is not information that you have made public; this is information your relatives have made public.

Research paper:

“Identity inference of genomic data using long-range familial searches.”

Abstract: Consumer genomics databases have reached the scale of millions of individuals. Recently, law enforcement authorities have exploited some of these databases to identify suspects via distant familial relatives. Using genomic data of 1.28 million individuals tested with consumer genomics, we investigated the power of this technique. We project that about 60% of the searches for individuals of European-descent will result in a third cousin or closer match, which can allow their identification using demographic identifiers. Moreover, the technique could implicate nearly any US-individual of European-descent in the near future. We demonstrate that the technique can also identify research participants of a public sequencing project. Based on these results, we propose a potential mitigation strategy and policy implications to human subject research.

A good news article.

The international digital human rights organization Access Now (I am on the board) is looking to hire a Chief Security Officer.

I believe that, somewhere, there is a highly qualified security person who has had enough of corporate life and wants instead to make a difference in the world. If that’s you, please consider applying.

Facebook Is Using Your Two-Factor Authentication Phone Number to Target Advertising

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/10/facebook_is_usi.html

From Kashmir Hill:

Facebook is not content to use the contact information you willingly put into your Facebook profile for advertising. It is also using contact information you handed over for security purposes and contact information you didn’t hand over at all, but that was collected from other people’s contact books, a hidden layer of details Facebook has about you that I’ve come to call “shadow contact information.” I managed to place an ad in front of Alan Mislove by targeting his shadow profile. This means that the junk email address that you hand over for discounts or for shady online shopping is likely associated with your account and being used to target you with ads.

Here’s the research paper. Hill again:

They found that when a user gives Facebook a phone number for two-factor authentication or in order to receive alerts about new log-ins to a user’s account, that phone number became targetable by an advertiser within a couple of weeks. So users who want their accounts to be more secure are forced to make a privacy trade-off and allow advertisers to more easily find them on the social network.

More on the Five Eyes Statement on Encryption and Backdoors

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/10/more_on_the_fiv.html

Earlier this month, I wrote about a statement by the Five Eyes countries about encryption and back doors. (Short summary: they like them.) One of the weird things about the statement is that it was clearly written from a law-enforcement perspective, though we normally think of the Five Eyes as a consortium of intelligence agencies.

Susan Landau examines the details of the statement, explains what’s going on, and why the statement is a lot less than what it might seem.

Major Tech Companies Finally Endorse Federal Privacy Regulation

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/09/major_tech_comp.html

The major tech companies, scared that states like California might impose actual privacy regulations, have now decided that they can better lobby the federal government for much weaker national legislation that will preempt any stricter state measures.

I’m sure they’ll still do all they can to weaken the California law, but they know they’ll do better at the national level.

Five-Eyes Intelligence Services Choose Surveillance Over Security

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/09/five-eyes_intel.html

The Five Eyes — the intelligence consortium of the rich English-speaking countries (the US, Canada, the UK, Australia, and New Zealand) — have issued a “Statement of Principles on Access to Evidence and Encryption” where they claim their needs for surveillance outweigh everyone’s needs for security and privacy.

…the increasing use and sophistication of certain encryption designs present challenges for nations in combatting serious crimes and threats to national and global security. Many of the same means of encryption that are being used to protect personal, commercial and government information are also being used by criminals, including child sex offenders, terrorists and organized crime groups to frustrate investigations and avoid detection and prosecution.

Privacy laws must prevent arbitrary or unlawful interference, but privacy is not absolute. It is an established principle that appropriate government authorities should be able to seek access to otherwise private information when a court or independent authority has authorized such access based on established legal standards. The same principles have long permitted government authorities to search homes, vehicles, and personal effects with valid legal authority.

The increasing gap between the ability of law enforcement to lawfully access data and their ability to acquire and use the content of that data is a pressing international concern that requires urgent, sustained attention and informed discussion on the complexity of the issues and interests at stake. Otherwise, court decisions about legitimate access to data are increasingly rendered meaningless, threatening to undermine the systems of justice established in our democratic nations.

To put it bluntly, this is reckless and shortsighted. I’ve repeatedly written about why this can’t be done technically, and why trying results in insecurity. But there’s a greater principle at first: we need to decide, as nations and as society, to put defense first. We need a “defense dominant” strategy for securing the Internet and everything attached to it.

This is important. Our national security depends on the security of our technologies. Demanding that technology companies add backdoors to computers and communications systems puts us all at risk. We need to understand that these systems are too critical to our society and — now that they can affect the world in a direct physical manner — affect our lives and property as well.

This is what I just wrote, in Click Here to Kill Everybody:

There is simply no way to secure US networks while at the same time leaving foreign networks open to eavesdropping and attack. There’s no way to secure our phones and computers from criminals and terrorists without also securing the phones and computers of those criminals and terrorists. On the generalized worldwide network that is the Internet, anything we do to secure its hardware and software secures it everywhere in the world. And everything we do to keep it insecure similarly affects the entire world.

This leaves us with a choice: either we secure our stuff, and as a side effect also secure their stuff; or we keep their stuff vulnerable, and as a side effect keep our own stuff vulnerable. It’s actually not a hard choice. An analogy might bring this point home. Imagine that every house could be opened with a master key, and this was known to the criminals. Fixing those locks would also mean that criminals’ safe houses would be more secure, but it’s pretty clear that this downside would be worth the trade-off of protecting everyone’s house. With the Internet+ increasing the risks from insecurity dramatically, the choice is even more obvious. We must secure the information systems used by our elected officials, our critical infrastructure providers, and our businesses.

Yes, increasing our security will make it harder for us to eavesdrop, and attack, our enemies in cyberspace. (It won’t make it impossible for law enforcement to solve crimes; I’ll get to that later in this chapter.) Regardless, it’s worth it. If we are ever going to secure the Internet+, we need to prioritize defense over offense in all of its aspects. We’ve got more to lose through our Internet+ vulnerabilities than our adversaries do, and more to gain through Internet+ security. We need to recognize that the security benefits of a secure Internet+ greatly outweigh the security benefits of a vulnerable one.

We need to have this debate at the level of national security. Putting spy agencies in charge of this trade-off is wrong, and will result in bad decisions.

Cory Doctorow has a good reaction.
